Verifying the communication
To verify that the rear communication with the SMS/SCS system is working, there are some dif-
ferent methods. Choose one of the following.
2.1
Verifying SPA communication
Procedure
1.
Use a SPA-emulator and send “RF” to the IED. The answer from the
IED should be “REx670 ”.
2.
Generate one binary event by activating a function which is config-
ured to an event block where the used input is set to generate events
on SPA. The configuration must be made with the PCM600 software.
Verify that the event is presented in the SMS/SCS system.
During the following tests of the different functions in the IED, verify that the events and indi-
cations in the SMS/SCS system are as expected.
2.2
Verifying IEC communication
To verify that the IEC communication with the IEC master system is working, there are some
different methods. Choose one of the following.
Procedure
1.
Check that the master system time-out for response from the IED, for
example after a setting change, is > 40 seconds.
2.
Use a protocol analyzer and record the communication between the
IED and the IEC master. Check in the protocol analyzer’s log that the
IED answers the master messages.
3.
Generate one binary event by activating a function which is config-
ured to an event block where the used input is set to generate events
on IEC. The configuration must be made with the PCM600 software.
Verify that the event is presented in the IEC master system.
During the following tests of the different functions in the IED, verify that the events and indi-
cations in the IEC master system are as expected.
